The shaft 18 does noteXtend beyond the side Walls of the brackets 3'and 4:,nor do the'hubs disposed within which theshaft 18 is j ournaled, extend beyond the side walls of the brackets?) and lithereby forming a truck that does not offer objectionable projections at the lowerend thereof. j

Heretofore it has been the'general custom for thetruckmen to grasp one hand" of the handle member when loading the truck and to 1 grasp with the other hand the upper end of the uprightsl and 2. This throws the body of the user of the truck out of balance." I have found that much better results are obtained and greater loads can be safely hauled V by inexperienced truckmen when'a cross bar 23 is secured to the uprights 1 and 2. The

cross bar 23 has a right angle formed at either 1 end to facilitate engagement with the uprights, in order that the truckmanmay ac- "commodate' the-location of the handle bar'23 to thedesiredposition. Adjusting holes 24 t are dis-posed within the side walls of the upa rights and thecrossbar 23 may be detaehably secured: thereto by removable fastenings, as
